We each contain a ruthless predator within, call it ambition or rage but it is there. Only with full control of this beast can we survive. That's why we have laws, so we don't bite each others' throats. The rule of law is all that separates us from the howling within. But the alphas make the laws and the other packmates follow, and the one holding the leash is often mistaken for the alpha.
Somewhere between humanity and the beasts, instincts must be wrangled to conform to law. Or is it the other way around?
